Refer to 49HOptional Equipment, page 50H3-53, for further information. 
The wire-ended encoder is connected to the Drive using a screened cable throughout its entire length to provide 
speed feedback. 
Terminals E1 (0V) and E2  (+24V dc) are the return and supply respectively. 
NOTE   The speed loop is set-up for the Encoder by the SPEED FBK SELECT parameter in the SPEED 
LOOP function block. Select ENCODER for this parameter. 
The maximum allowable encoder frequency is 100kHz, thus with a standard 1000 lines per revolution encoder the 
motor speed cannot exceed 6000 rpm. 
For specification and connection information refer to Parker SSD Drives or the appropriate Technical Manual.
